Abstract

Mitigation of inter-base station resynchronization loss in wireless networks including contention-based shared frequency spectrum is discussed. Aspects of such mitigation provide for base stations entering into an idle mode when a transmission opportunity occurs in a radio frame of the next resynchronization occasion. Additional aspects provide for the base station to signal a flexible listen before talk (LBT) frame length to the user equipment (UE), either with or without explicit signaling of the downlink-uplink division. Further aspects provide for the base station to signal a reset indication to UEs that will prompt the UEs to monitor for downlink channel reserving signals prior to the current LBT frame ending by the resynchronization occasion.
